GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 368,831, dated Augu 1887- Applieation filed March 30, 1887. Serial No. 232,993.

[0 all whom it may concern.-

Be it known that I, BENJAMIN F. FERTICK,

a citizen of the United States, residing at (30- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Gas-Regulators, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a central vertical section of a regulator embodying my improvement. Fig. 2 is a horizontal section on line :0 as, Fig. 1. Fig. 3 is a horizontal section on line 3 y, Fig. 1.

.Like referenceletters indicate like parts in all the figures.

A is the lower part of the body.

B is the inlet-pipe through which gas is admitted, and is preferably attached to the outlet-pipe of the meter; but it may be placed at any convenient point.

0 is the intermediate part of the body, made funnel-shaped, and at its lower end fitting the upper end of the part A, which may also be funnel-shaped, as shown.

Dis the upper part of the body, and E is the cap or cover.

By making the sections A O D all funnelshaped-that is, so shaped that the walls converge downwardly-I effect a saving of ma terial, attain convenience in putting them together by solder or otherwise, and make a more artistically-shaped body.

a is the outlet for the discharge of such material as may be deposited or accumulate at that point, there being a pocket or trap formed there by reason of the inlettube B projecting some distance above the bottom of the lower section, A, of the body.

F is a transverse partition or diaphragm, below which is an inlet-chamber, F. G is a similar transverse partition, there being an outlet-chamber between the two partitions,and marked G.

g is a tube projecting upward from the dia phragm G and substantially concentric to the walls of the body of the device.

H is a smaller tube within the tube 9 and concentric thereto, but longer, and extending down through the outlet-chamber and the diaphragm F some distance into the inlet-chamber F.

75 is a V-shaped upward-inclined slot or (No model.)

throat formed in that part of the tube H which projects below the diaphragm F.

I is a gasometer or hollow funnel-shaped float, the lower open end of which fits somewhat closely to the outer surface of the tube 9.

Jj is a valve fitting closely inside the lower end of the tube H, the downward-projecting tubular flanged part 3 of the valve engaging with the inner surface of the tube, so as to insure a proper working relation between these parts.

J is a valve-rod formed in two parts, and hinged atj", the upper end of the rod being firmly connected with the upper part of the float, preferably by means of nuts jj' and a packing-washer or other contrivance to prevent leakage. When the valve is made tubular, as described, or formed withadownwardlyextending tubular flange or with other equivalent devices, it is provided with a long bearing on the valve-tube, and this, in conjunction with the hinging of the two parts of the valve-rod, avoids all cramping or binding of the valve if the float should oscillate, as it frequently docs.

K K is a duplex coiled spring, of which the part K is so much larger in cross-diameter than the part K that there shall be no interfcrence when in practical operation.

L is a screw-th readed rod.

M is a bracket or supporting bar or plate supported upon or within the upper end of the body. The threaded rod passes through the bracket or bar M, and carries two adj usting-nuts, Z Z, by means of which the vertical position of the bar relative to the other part may be determined.

Vhen prefcrred,the valve J may be screwed onto the lower end of the valve-rod or other wise adj ustably attached to it.

My object in making the spring in two eoncentric coils is to secure a desired flexibility,

elasticity, and freedom of movement; but I do not Wish to be limited to the use of such double spring,because under many circumstances and conditions an ordinary single spiral spring will answer a very good purpose.

In operating my invention I purpose to fill the chamber D,Which is above the diaphragm or partition G,with glycerine or other suitable liquids up to about the point indicated by the the gasometer will tend to lift the valve above.

the upper end of the V-shaped slot h, and thus prevent gas from passing through the tube H;

but the position of the valve can be adjusted,

' so that under ordinary circumstances it will remain at some distance below the upper end of that slot. Therefore gas will flowin through the inlet-tube l3, thence through slot h, out at the upper end of tube H into the float, down through the annular space between the tubes 9 H into the outlet-chamber G, and thence through the eduction-tube c.

As will be readily understood, the pressure within the float will tend to lift it out of the surrounding liquid and close or partially close the valve, thus reducing the size of the passage-way for gas through the V-shaped slot; and the consequent closing of the valve can be so regulated by means of the adjusting devices and the depth of the liquid as to maintain a practically-uniform pressure of gas at the burner.

While I prefer to use a V-shaped slot in the tube H, with a valve, J j, and a cap or plate, h, closing the lower end of the tube, yet I do not wish to be limited thereby, because many modifications of these parts might be adopted by any skilled mechanic without departin from the spirit of my invention.

I am aware of the fact that use has been made heretofore in gas-regulators of a'materially different type of a float with downwardly-converging walls,in combination with an interior body or casing for the liquid-chamber, also having downwardl y-convergin g walls; but the regulators so used have been differently constructed from the one herein and have operated upon a difierent principle, in that the chamber within the float has been merely a recoil-chamber--that is to say, not a chamber into which all of the gas is taken in a current and from which it .is withdrawn as it passes to the burners, but one in which a volume of gas is retained more or less permanently,with the expectation that its pressure will vary sufficiently to properly modify the volume of incoming gas. In the present device the parts are so constructed and related that all of the gas is carried from the inletorifice to the interior of the float, and is thence taken to the eduction-pipe, so that the float is much more easily affected by any variation in the pressure of the gas than is the case where the float is simply a recoil-chamber, and by having the exterior casing or body formed with downwardly-converging or conical walls I can not only insert and attach the various tubes with ease, but can also dispense with, a large part of the glycerineor liquid which has been heretofore necessary in devices of this-sort.-

What I claim is- 1. In a gas-regulator, the combination of the inclosing-body, the diaphragm F, the tube H, rising therefrom and projecting below the diaphragm and provided with the V-shaped slot, the float, and the valve arranged within the tube H, substantially as set forth.

2. In a gas-regulator, the combination of the inclosing-body,the inlet-duct,the liquid-chamber, the float therein, the valve-tube extending continuously from the inlet duct or chamber to the interior of the float, said tube having a tapering passage-way through its wall at or near its lower end to vary the amount of gas admitted, the concentric tube extending from the interior of the float to the outlet-duct, the valve situated in the said valvetube and connected with the float, and the adjustingspring connected with the float, substantially as set forth.

3. In a gas-regulator, the combination of the liquid-chamber having downwardly-converging-walls, the float therein having downwardly converging walls, the inlet duct or chamber, the valve-tube extending continuously from the inlet duct or'chamber to the interior of the float,through which all of the gas is taken into said float, the outlet-duct from the interior of the float, the valve in the said valve-tube connected with the float, and the spring connected with the float, substantially as set forth.

4. In a gas-regulator, the combination,with the gas-passages, the float, and the valve-tube having its upper, end opening into the float, and provided at its lower end with a horizontal gas-inlet, of the imperforate valve arranged inside said tube, substantially as set forth.

5. In a gas-regulator, thecombinatiomwith the gas-passages and the outlet-duct, of the float, the valve-tube, the valve below the float having a tubularflange fitted to thevalvetube, and the rods hinged together and joining the float to the valve, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
